Abstract

This study aims to determine the effect of compost and biochar doses and their interactions on the growth and yield of shallots. This research was conducted at the Local Waste Processing Site (TOSS), Kusamba Village, Dawan District, Klungkung Regency, Bali Province. The design used in this study was a factorial randomized block design (RAK) consisting of 2 factors. The first factor is the treatment of compost dose (K) which consists of 3 levels, namely: K1 = 5 tons ha-1, K2 = 10 tons ha-1, and K3 = 15 tons ha-1. While the second factor is the dose of biochar (B) which consists of 3 levels, namely: B1 = 5 tons ha-1, B2 = 10 tons ha-1, and B3 = 15 tons ha-1. The interaction between compost treatment with biochar had a significant (P<0.05) effect on the fresh weight of tubers per clump and fresh weight of rhizomes per clump, and a very significant effect (P<0.01) on the number of tubers per clump, but not significant (P≥0.05) to other variables. The compost dose treatment had no significant effect (P≥0.05) on all observed variables except for the maximum number of leaves. Biochar dose treatment had a significant to a very significant effect on the variables of maximum leaf number, fresh weight of tubers per clump, the oven-dry weight of tubers per clump, and oven-dry weight of tubers per clump, and had no significant effect (P≥0.05) on other variables. The interaction between compost 5 tons ha-1 and biochar 10 tons ha-1 (K1B2) gave the highest fresh weight of tubers per clump of 100.00 g which was significantly different or increased by 38.60% compared to the lowest fresh weight of tubers per clump at the interaction of compost 5 tons ha-1 with biochar 15 tons ha-1 (K1B3) is 72.15 g.

Abstract

Pig livestock is one of the livestock developed in Indonesia because it can adapt to environmental conditions, has good production and reproduction properties including fast growth so that the body matures and quickly, the number of liters of labor size is large, birth weight and weaning weight are high, meat production is high and can also meet human needs. To meet human needs for protein and the economy, it is necessary to increase the production and productivity of pig livestock by paying attention to reproductive aspects, and nutrition. This study aims to determine the influence of the time interval of male mating in nature which affects the conception rate, liter size, and mortality. This research was carried out in Catur Village, Kintamani District, Bangli Regency from April to August 2022. This study uses a quantitative descriptive method by mating males at time intervals and observing the results directly. The number of livestock used in this study was 6 landrace sows consisting of 1 sow mated with males at intervals of once a week, 2 heads mated at intervals twice a week, and 3 heads mated at intervals of three times a week. The variables observed in this study were conception rate, liter size, and mortality. The results showed that the interval of mating time influenced the conception rate value and the number of liters of size. The best interval from the results of this study is one mating in a week, namely a conception rate of 100%, the number of liters size 9 heads. And the time interval of mating has no effect on the mortality of the child at birth.

Abstract

This study aims to determine the effect of compost fertilizer and NPK fertilizer on the growth and yield of Shallots. This research was conducted at the Local Waste Processing Site, Kusamba Village, Klungkung. This experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors. The first factor was the dose of compost (T) consisting of 3 levels, namely: 5-ton ha-1 (T1), 10-ton ha-1 (T2), and 15-ton ha-1 (T3). The second factor is the dosage of NPK fertilizer (M) consisting of 3 levels: (M1) 150 kg/ha-1, (M2) 300 kg/ha-1, (M3) 450 kg/ha-1. The interaction between compost treatment and NPK had a significant (P<0.05) to very significant (P<0.01) effect on all observed variables except fresh weight per clump. The highest fresh weight of tubers was obtained from the interaction between compost 5 tons ha-1 and NPK 150 kg ha-1 (T1M1) giving the highest fresh weight of tubers per clump, 41.44 g, significantly different or an increase of 45.13% compared to the fresh weight of tubers. The lowest per clump was the interaction of 15-ton ha-1 compost with NPK 450 kg ha-1 (T3M3), which was 31.25 g.

Abstract

This study aims to provide a business strategy for laying hens in the New Normal era in the Province of Bali. This research is expected to produce recommendations for the right strategy to be applied to laying hens in the Province of Bali to help farmers face the New Normal era and able to increase breeders' income. This research was conducted in 3 central districts of laying hens in Bali Province using a survey method. The research location was determined by purposive sampling technique. The results of the IFAS-EFAS analysis showed an internal factor value of 3.65 and an external factor value of 3.31 indicating the position of the laying hen business in Bali Province is in quadrant I, namely growth and build strategy. Alternative strategies that need to be increased more intensively are: 1) Expansion of market share outside Bali (West Region to Jakarta and Eastern Region to East Nusa Tenggara), 2) Expansion of business scale by increasing capital, 3) Selecting less productive laying hens.

Abstract

The pumelo population in Bali is declining one is caused of a lack of good-quality seeds. This research was conducted to determine the effectiveness of organic coal fertilizer and rabbit farm waste as organic fertilizers for the growth of pomelo grafting seedlings. The research design used a nested pattern randomized block design with 3 replications. There are two factors, the first factor is the type of fertilizer, which are Coal fertilizers, Rabbit Farm Waste fertilizers, and Cow Manure fertilizers. The second factor is the dose of each type of fertilizer which consists of 3 levels, namely: 10 tons/ha; 20 tons/ha; and 30 tons/ha. The results showed that the effectiveness of the treatment of the type of organic fertilizer and the dose of the type of organic fertilizer had no significant effect on all observed variables. This shows that both coal fertilizer and rabbit manure have almost the same quality as cow manure in influencing the growth of pomelo seedlings. The effectiveness of fertilizers tested on the average shoot length of grafting tends to show the highest yields obtained at the highest dose (30 tons/ha), namely Coal fertilizer which is 28.80 cm, rabbit manure is 31.87 cm, and cow manure obtained is 28.13 cm.
